- ✓ Project, product and material specifications
- ✓ 3D CGI visualisations for every designed room / functional area — at no additional charge

Discuss my whole-house designUnderstanding area counts
Open plan? Count the functions.
Kitchen, living and dining count as three separate design areas even when they share one open-plan space. The counting rule applies to both the design fee and CGI incentive eligibility.
Example A / Four areas
Kitchen + living + dining + bedroom
Three open-plan functions and one bedroom = four designed areas. Design plus one half-price CGI: £1,850 ex VAT£2,220 including VAT.
Example B / Five areas
Kitchen + living + dining + two bedrooms
Three open-plan functions and two bedrooms = five designed areas. Design plus one included CGI: £2,000 ex VAT£2,400 including VAT.
Clear terms, no surprises
Common questions.
Can I commission only a measured survey?
Our normal architectural appointment combines the measured survey with initial design work under an agreed fixed-fee scope. It is not being advertised as a separate survey-only promotional product.
Do I have to appoint later RIBA stages?
No. Later stages are optional, subject to a separate written appointment. The £200 ex VAT£240 including VAT and £800 ex VAT£960 including VAT credits are available only if the relevant subsequent stage is appointed and the final eligibility terms are met.
Is the project-management fee included in the architectural design fee?
No. Construction-stage project management covering RIBA Stages 5–6 is optional and quoted separately. Any fee percentage, cost basis and detailed responsibilities will be agreed in writing. RIBA Stage 7 aftercare is not included unless separately appointed.
What does an additional concept refinement cover?
One further preliminary concept direction or refinement is included if the initial options have not adequately addressed the original agreed written brief. Changes to the brief or repeated redesign would be separately scoped.
What is included in the £400 ex VAT£480 including VAT interior design fee?
Interior design, 2D drawings, and product and material specifications for one agreed room or functional area. CGI is ordinarily separate, except where a qualifying promotional tier applies. Purchases, installation and specialist services are excluded.
Is an open-plan kitchen, living and dining room one area?
No. Kitchen, living and dining are three distinct functional design areas even when physically open-plan. Each separately designed area is charged and counted towards the CGI incentive.
How is the full-house CGI package different?
For an entire home with more than three bedrooms, when Horizon is appointed for the interior design of the entire home, CGI views of every commissioned room or functional area and one printed design book after the final revision are included at no additional charge. The number of viewpoints, revisions and book format will be stated in the written quotation.
Are approvals, engineering, construction and materials included?
No approval is guaranteed. Statutory fees, engineering, specialist consultants, material purchases, supply, installation and construction works are separately scoped unless expressly included in an appointment.
Offer terms: Fees are shown excluding VAT first, alongside the total including VAT at the current standard rate unless otherwise indicated. Each service is subject to site suitability, a written scope and a formal appointment. CGI view counts, refinement rounds, payment milestones and printed-book format will be specified before you instruct the work. Offers cannot be combined unless confirmed in writing.
